JAMES M. GRAY, OF ATLANTA, GEORGIA.

FASTENER FOR CAR-DOORS.

Specification of Letters Patent.

Patented July 113, 1915.

. Application filed July 1, 1914. Serial No. 848,428.

To all whom it may concern Be it known that I, JAMES M. GRAY, a citizenof the United States, residing at Atlanta, in the county of Fulton andState of Georgia, have invented new and useful lmprovements in Fastenersfor Car-Doors, of which the following is a specification.

This invention relates to improvements in locking means for the slidingdoor for a freight car to secure the same in closed posi tion and alsoin open position; the invention also relating to the provision ofimproved means for closely wedging the door when in closed position andfor drawing the door closely against the outer side of the door frame soas to close the cracks around the door and prevent loss of material,such as grain or the like in bulk from the car.

The invention consists in the construction, combination and arrangementof devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a portionof a wall of a freight car provided with an improved car door and doorhanging and securing means constructed in accordance with my inventionand showing the door in closed and locked position. Fig. 2 is a similarview of the same, showing the door in open position. Fig. 3 is ahorizontal sectional view taken on the plane indicated by the line 33 ofFig. 1. Fig. 4 is a vertical sectional view taken on the plane indicatedby the line 4-4 of Fig. 1. Fig. 5 is a detail perspective view of thelocking bar. Fig. 6 is a detail outer edge view of the door.

For the purposes of this specification a car wall is indicated at 1,provided with a door opening 2 around the sides of which, and on theouter side of the wall, is a door frame 3. On the outer side of the doorare reinforcing bars 41 appropriately spaced apart and cross sectionallyT-shaped. The opposite ends of the reinforcing bars 41 extend across theouter edge of the door and are provided with clips 44. A verticallymovable locking bar 45 is arranged to operate in the said clips, thelatter forming guides for said locking bar. The lower portion of thelooking bar is formed with a rack 46 which operates between a pair ofbrackets 47 that are secured on the outer edge of the door and betweenthe said brackets there is mounted an operating lever 48 which has apinion 49 at its pivotal endand which pinion engages the rack 46. Hencethe locking bar may be raised and lowered by the turning of the lever 48to cause the rack and pinion to coact and when the lever is raised tolower the locking bar its upper end passes between a pair of spaced lugs50 with which the looking bar is provided, the said lugs and the leverhaving alining openings through which a sealing strip 51 or othersuitable looking or securing device may be passed. If it is desired touse a lock to secure the lever'in such position the shackle thereof maybe passed through said openings.

The locking bar is provided with locking lugs 52 which are wedge shapedand which ooact with looking plates 53 and a lock rail 54 to lock thedoor in closed position. The lock plates and lock rail are secured onthe wall of the car as shown and have beveled inner ends 55 which coactwith the wedge shaped locking lugs 52 of the locking bar to secure thedoor in closed position, when the said locking lugs drop in front ofsaid plates and rail, and owing to the beveled edges or inclined edgesof said plates, rail and looking lugs, the locking bar when thusarranged. firmly wedges the door in closed position and against the stopbar 11.

The bar 37 and the web 36 of the bar 34 are provided with notches orrecesses 56 to clear the locking plates 58 and locking rail 54, and whenthe locking bar 45 is raised so that its locking lugs 52 are higher thansaid plates and rail the door may be then opened and may be moved untilit engages a stop 57 which is secured on the car wall at a suit abledistance from the door opening. The rail 54 bears under the uppermostlug 52 when the door is being opened, said lug sliding on said rail andwhen the door reaches fully opened position said uppermost lug clearsand drops from the outer end of said rail, thereby permitting thelocking bar to drop behind the outer end of said rail and thereby firmlysecure the door in opened position. A gravity catch 58 is provided,which is pivotally mounted on the outer edge of the door as at 59 andwhich is adapted to drop to a position above the lugs 50 of the lockingbar to secure the latter in lowered, locking position, either when thedoor is open or when it is closed. The bar 20 at the lower side of thedoor is provided at one end with a stop 60 which limits the extent ofdownward movement of the lever 48.

Having thus described my invention, I claim 1. In a structure of theclass described the combination of a wall having a door opening and astop device at one side of the door opening, a slidable mounted doormovable across the door opening, a vertically movable locking barcarried by the door and provided with wedge-shaped lugs, and lookingdevices on the wall,v spaced from one side of the door opening andarranged to coact with the wedge-shapedlugs of the locking bar to securethe door in closed position and to also firmly wedge the door againstthe said stop device.

2. In astructure of the class described the combination of a wall havinga door opening and a stop device at one side of the door opening, aslidably mounted door movable across the door opening, a verticallymovable locking bar carried by the door and provided with wedge-shapedlugs, and locking devices on the Wall, spaced from one side of the dooropening and arranged to coact with the wedge-shaped lugs of the lockingbar to secure the door in closed position and to also firmly wedge thedoor against the said stop device, one of said locking devices on thewall being a rail which also'coacts with one of the lugs ot the lockingbar to hold the latter in raised posi tion while the door is beingmoved.

8. Ina structure of the class described the combination of a wall havinga door openingand astop device at one side of the door opening, aslidab'ly mounted door movable across the door opening, a verticallymovable locking bar carried by the door and provided with wedge-shapedlugs, and looking devices 'on the wall, spaced from one side of the dooropening and arranged to coact With the wedge-shaped lugs of the lockingbar to secure the door in closed position and to also firmly wedge thedoor against the said stop device, one of said locking devices on thewall being a rail which also coacts With one of the lugsof the lockingbar to hold the latter in raised position while the door is being moved,the length of said rail being-such that when the 'door .is fully openedsaid lug clear-s and drops in front of the outer end of said rail andcoacts therewith to lock the door in open position.

.4. Ina structureo'f the class described thc combination of a Wallhavinga :door :opening and also having a fixed locking device, a door mountedfor sliding movement across the door opening, a locking bar mounted forvertical movement on the outer edge of the door and having means tocoact with said fixed locking device on the wall to lock the door inclosed position, said locking bar having a rack, a pinion engaging therack and mounted in hearings on the door, and a lever to actuate saidpinion to raise or lower said locking bar.

5. In a structure of the class described the combination of a wallhaving a door opening and also having a fixed locking device, a doormounted for sliding movement across the door opening, a locking barmounted for vertical movement on the outer edge of the door and havingmeans to coact with said fixed locking device on the wall to lock thedoor in closed position, said locking haihaving a rack, a pinionengaging the rack and mounted in hearings on the door, and a lever toactuate said pinion to raise or lower said locking bar, a locking baralso having a pair of spaced lugs between which the upper end of thelever moves when the loching bar is lowered, said lugs and bar havingcoincident openings to receive a sealing device.

6. In a structure of the class described the combination of a wallhaving a door opcning and also having a fixed locking device, a doormounted for sliding movement across the door opening, a locking barmounted for vertical movement on the outer edge of the door and havingmeans to coact with said fixed locking device on the wall to lock thedoor in closed position, said locking bar having a rack, a pinionengaging the rack. and mounted in hearings on the door, and a lever toactuate said pinion to raise or lower said locking bar, a locking baralso having a pair of spaced lugs between which the up per end of thelever moves when the locking bar is lowered, said lugs and bar havingcoincident openings to receive a sealing de vice, and a gravitatingcatch carried by the door and adapted to close above the lugs to preventcasual lifting-of the locking bar.

In testimony whereof I afiix my signature "in presence of two'witnesscs.
